My first recommendation would be to not buy speakers going just by reviews. If you end up with something you like it will be more of an accident than anything else.
Given the choices you list, I would go with the Model 2's. I have them in my main system and know them very well. If you match your components well and set them up properly, they will sound amazing. The Quatro and Treo are also very good but I like the Vandersteen's that don't have a traditional box. You'll save a lot of money also. The 2's will do most things better that the Aerials. The Aerials will play louder and go a little deeper in the bass.
